FLUSHING DEVICE FOR WATER-CLOSET BOWLS.

SPECIFICATION forming part of Letters Patent No. 514,245, dated February6, 1894.

Application filed June 1, 1892. Serial No. 435,167. (No model.)

To all whom it may concern: Be it known that I, EDWARD G. Srovnn, acitizen of the United States, and a resident of the city of Trenton,county of Mercer, and State of New Jersey, have made certain new anduseful Improvements in Flushing Devices for Water-Closet Bowls andSimilar Articles, of which the following is a specification. The objectof my invention is to provide a more perfect means of securing ametallic pipe to an earthenware nozzle and one that can be very readilyapplied to such nozzles. My invention, though more particularlyintendedas a flushing device for water=closet bowls, may be applied withequal facility to other sanitary appliances, and in fact to anystructure where a water tight joint is desired between a metallic ornon-metallic pipe and earthenware.

In the accompanying drawing, A is the projection from a water-closetbowl which is generally termed a horn provided with the overhanging rimB.

O is a short piece of pipe or elbow serving as a connecting link betweenthe horn and the flushing pipe not shown. This elbow may be made ofmetal, rubber or any other desired flexible or non-flexible material andis provided with a projecting flange at each end. The flange, a, ispressed against the earthenware of the horn, while the flange, a, iscoupled with the flushing pipe in any well known manner.

My invention consists in securing this elbow and the earthenware nozzletogether as a water tight joint by means of two collars threaded uponeach other and each bearing an annular flange or projecting lugs. Thecollar D is set around the elbow O in such-a way that its projectinglugs or flange, b b, bear againstthe flange, a, of the elbow and hold itagainst the earthenware nozzle. This collar, D, is externally threadedas a malescrew and is made to project somwhat farther along the elbow,C, than the other collar, E, which is threaded as a female-screw, theprojecting lugs or flange of which, 0, are designed to bear against theinner surface of the overhanging projecting rim, B. It is obvious thatthe pressure which holds the flange,

a, of the elbow 0, against the earthenware, is created and increased byturning the'collar D, and thereby, by reason of the interlockingscrew-threads, of the collars, D, and E, moving their flanges inopposite directions. These two interthreaded collars might be used ifdesired, for connecting the flushing pipe dir ectly to the nozzlewithout an intermediate pipe or elbow O.

A convenient method of inserting the flanged pipe 0 and the flangedcollars D and E, in the recess of the earthenware nozzle, under theoverhanging rim B, is by making the opening of said nozzle and theperiphery of the flanges of longer diameter in one direction than inanother, as shown in the patent of Herbert Machin, No. 398,838, datedMarch 5, 1889. Another convenient method is that shown in the patent ofThomas Kennedy, No. 45,836, dated January 10, 1865, wherein passages areleft open for the projecting lugs or flanges b-b. But other methods ofintroducing these flanged pipes and collars into the nozzle may beemployed, if desired.

I do not claim broadly in combination with an earthenware bowl or likearticle having a mouth provided with a seat at the base, a washerfitting against the seat, a ring within said mouth engaging bya bayonetjoint with the bowl, and a nipple engaging with the ring to compress thewasher against the seat of the bowl.

I claim- A flushing device for water closet bowls, which consists of anearthenware nozzle, provided with an overhanging rim and a flanged pipesurrounded by two interthreaded flanged collars inserted in said nozzleand under said overhanging rim; each collar being provided with a spudprojecting outside of said nozzle, whereby, when one of saidinterthreaded flanged collars is turned, the flange of one collar forcesthe flanged pipe against the nozzle and the flange of the other collaris forced against the under side of said overhanging rim, as and for thepurpose specified.

EDWARD O. STOVER.
